Don't know why is that happening but try to convert that file in other type as 3ds and than try to import into SU.

If you editing same file that you share on warehouse than with shetch up just go on share model,model would be changed but all info would stay as rating and comments.
But if you mada a new model most likely that you need to delete a old one.

Right mause button on photo,than go on properties.
There go on change and select program depend what you have,windows paint or something similar.
Jpeg is not a model it's a photo,you could import into sketch up but not open it with sketch up.

If you don't need to render than you don't need it...no need for buy.
Sketch Up will work and without it.
For remove go on Control Panel and Add or Remove Programs,find there V-Ray for Sketchup and just Remove.

OK...

Hi there.

I'v notice that clicking on any link it's get opened in same window or same tab.
On Opera I have option open in new tab or background tab,that make very easy to go on link in another tab without interrupting main opened tab.
Lot's of other forum have that option,clicking on link that get opened in new tab.
Much better way for using link,so maybe you could think to try that option and here.

Thanks.

Most likely that's file is damage,no help in that case.

Go on Plugin than on Podium and show...

When you push-pull circle than just intersect with model.
Check link...

You group parts,maybe that's why you can't push-pull.

Try to make like this - video:http://rapidshare.com/files/130413438/like_this.rar

Sorry but your model is full od double-side,uneded faces,maybe there are a easyer way how to made this is mine,or how I would do it.

I'm not good with texturing in sketch up,but what I notice that Google Shetch Up 6 had terrible 3DS exporter,so I use Sketch Up 5,give much better and quality export...don't know maybe that's one peace of exporting problem.
One more thing,some model part could be transparent after exporting,it's beacuse you need to all out faces been proper turn,when you create box or any shape make shure that are faces turn properly.

Here's another intresting way of viewing 3d model...

I must be missing something here. Why wouldn't you just change the number of segments in the arc before drawing it?
